BZZZT | PC/Mac/Linux/Steam Deck

BZZZT is a fast-paced "jump-dash-run" retro game with a fresh and modern design made almost single-handedly by one solo developer, Karel Matejka, known as Ko.dll.

Inspired by the 80's tech revolution, this beautiful pixel-art precision platformer transports you back in time with a brand new adventure, paying homage to the popular and much loved gaming designs of the past.

Face deadly traps, use your special abilities, jump through a series of testing chambers and prove you can fully control your newly obtained robotic body.

The year is 4096.
In a top-secret laboratory, inventive Doctor Emily and world-renowned Professor Norbert are working on a highly classified project. Through their joint research and intellect, they finally created a tiny robot with a big AI personality! No larger than a regular household toaster, but with some extraordinary skills, ZX8000 is ready to save the world, one platform challenge at a time!

Meanwhile, other dark influences are at play in the world of BZZZT. The evil mad scientist, Badbert, prepares to unleash his nefarious plans upon an unsuspecting world as soon as he finds the perfect equilibrium of darkness, malice and madness. Bwahahaha.

Grab your controller or keyboard and navigate ZX8000 to complete his missions and thwart Badbert's evil plans!

Karel Matejka, known as KO.DLL, is an artist who started his career as an illustrator and a graphic novel artist. Soon after he got in touch with the first computers, he started making games, which earned him the status of one of the first pioneers who started the gaming industry in the Czech Republic. His unique and multi-genre art style brought him worldwide popularity. Although his main passions are all art forms, he's also a coder, a game designer, a terrific chef, and a dedicated friend. And above all, he's a hard-working game lover with a dream to make games the old way again and pay homage to all the great games from the '80s that - like for so many of us - have formed his style and passions.

He has worked on titles such as Mafia, Operation Flashpoint, ArmA, Memento Mori 1 and 2, Star Wars: Assault Team, Nemo's Reef, Toy Story: Smash It, and over 20 others. It was the accumulated experience of more than 30 years and the endless enthusiasm that allowed him to start this solo project - a game he himself defines as "a time machine back to the 1980s".
